SPECIFICATION forming part of Letters Patent No. 446,161, dated February 10, 1891.

Application filed August ll, 1890. SerialNo. 361,717. (No model.)

T0 all whom, it may concern.:

Be it known that I, LIBBEUs CHILsON, a citi- Zen of the United States, residing at Vorcester, in the county of IVorcester and State of Massachusetts, have invented certain new and useful Improvements in Railway-Joints; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

M v invention relates to railway-joints, and more particularly to the coupling or chair for connecting the ends of the rails.

rThe object of my invention is to improve upon the construction of rail-joints and to make a rail coupling or chair to connect the ends of rails, which shall be strong and durable, and to connect the contiguous ends of rails in such a manner as to prevent any end displacement of the rails, either in a vertical or in a horizontal plane, and secure the ends of the rails firmly to the ties or sleepers of the track.

My invention consists incertain novel features of construction of rail-joints, and more particularly of rail couplings or chairs, as will be hereinafter fully described.

Referring` to the drawings, Figure l. is a plan view of a railway-joint of my improved construction. Fig. 2 is a side view, partially in section on line x zr, Fig. 1, looking in the direction of arrow o, same figure. Fig. 3 is a cross-section on line 'y y, Fig. 1,1ooking in the direction of arrow Z), saine iigure, and Fig. 4 is a plan view of the rail coupling or chair detached.

Inthe accompanying drawings, 1 and 2 are the adjoining or contiguous ends of two rails. Said rails are made hollow or provided with a vertical slot 3 at their ends, extending longitudinally in the under part thereof, as shown in Figs. 2 and 3. The upper or bearing surface 4 of the rail is connected with the lower surface or flanges 5 5 of the rail by the double web or extensions G 6, as clearly shown in Fig. 3.

I have shown in Fig. 1 the ends of the rails 1 and 2 made to overlap each other; but they may be made to abut against each other in -show-n in the drawings.

the ordinary way, if preferred, as shown in side View, Fig. 2. The contiguous ends of the rails 1 and 2 are secured together by means of the coupling or chair 7, made of castor malleable metal, of substantially the shape shown in the drawings, consisting of a base part or bed S, preferably made of sufficient length to extend across two ties 9 and 10, as The base 8 rests upon the ties, and is provided with a central longitudinal rib or projection 11, preferably made integral therewith and extending np- .ward from the 'central part thereof. The central rib 11 of the chair 7 is adapted to extend within the vertical slots 3 in the ends of the rails 1 and 2. The height of the rib, 11 corresponds with `the depth of the slots 3 in the ends of the rail, as shown in Fig.- 3.

On each side of the central longitudinal rib 11 of the chair 7 is a projection or shoulder 12, preferably made integral with the base 8 and adapted to abut against the outer edges of the rail-flanges at the point where the rail ends meet, as shown in the drawings. The central rib 11 of the chair 7 is provided with elongated holes 13 tl1erein,through which the bolts 14, headed at one end and provided with nuts at the other end, extend.

The bolts 14 serve to secure the ends of the rails 1 and 2 to the central rib 11 of the chair 7. Elongated holes 13 in the central rib 11, through which said bolts extend, allow of the expansion and contraction of the rails in the ordinary way.

The rail-chair 7is preferablyprovided with holes 15 therein, through which the spikes 16 pass and are driven into the ties for the purpose of securing the chair and the rails att-ached thereto to the ties, as shown in Fig. 3.

The advantages of my improved construction of rail couplings or chairs will be fully appreciated by those skilled in the art.

By means of my improved rail coupling or chair, having the base part or bed S adapted to extend over the ends of two ties and to be spiked thereto, and having the central longitudinal rib 11 extending up from said base part and adapted to extend within the vertical slots 3 in the adjoining ends ofthe rails, I am enabled to secure the ends of said rails together without employing any fish-plates,

ordinarily employed, and in sueh a manner that the ends of the rails Cannot move out of line Witheach other in a horizontaler Yertical plane.

Having thus described niyilvlvention, what I claim as new, and desire to secure by Letters Patent` is- 1. As an improved artiele of manufacture, a rail coupling` or chair having its base or bed 8 of sufeient length to extend over the ends of two ties, a central longitudinal rib made integral With said base and extending up therefrom for the purpose stated, and provided With elongated holes 13, and the projeetions or shoulders 12, extending upon opposite sides of the central rib 11, for the purpose stated, substantially as set forth.

With and adapted to extend into the Vertical` slots 3, and the elongated holes 13 in said rib, and the projections or shoulders 12 on the base part, for the purpose stated, and bolts 14, all combined together substantially as set forth.
